Bodycam shows driver barreling SUV at Okla. cop

Body camera video shows the scary moments an Oklahoma police officer faced down an SUV barreling right at him. Sand Springs Master Patrol Officer Matt Stacy had about three seconds to react. The driver of the stolen SUV steered directly at his cruiser.

With the vehicle bearing down on him, Stacy fired his gun twice before impact.

Stacy was knocked to the ground, with the vehicle traveling at an estimated 50 mph, reports CBS News correspondent Omar Villafranca.

Another vantage point from the officer who was chasing the suspect showed him with his gun pointed at the driver.

"Show me your hands! Put your hands up now!" the officer could be heard saying.

Stacey Ann Bunsey, 41, popped out of the vehicle's sunroof and said she was "god." Bunsey told officers "Welcome to hell" before she was tased in the chest.

Officers had to go in through the roof to get her out of the vehicle.

An unemployed Alaska native, Bunsey is being held on nearly $80,000 bond. She's expected to be charged with four felonies and a misdemeanor -- including assault and battery with a deadly weapon on a police officer.

Police suspected she was under the influence of methamphetamine because she used "street slang" when she "...stated that she 'did some ice' a couple of days ago. She then stated that she 'did a line of ice last night...'"

"That wasn't the sound of braking, that was the sound of an accelerator," Sand Springs Police Chief Mike Carter said.

A four-year veteran of the Sand Springs police department, Stacy suffered minor scrapes to his head, forearm and right hand.

"Our worry at the time was he was severely injured -- he wasn't. I can just tell you my only explanation for that is he was under the protection of God because he very well should have been dead," Carter said.
